Answer:
a) Equation: 9x+9 = 72
b) x =7
Step-by-step explanation:
The total cost of 9 bracelets = $72
Shipping charge = $9
a) Define your variable and write an equation that models the cost of each bracelet.
Let x be the cost of one bracelet, the equation will be
9x + 9 = 72
As 9 bracelets were there and the shipping cost was 9 and total cost was 72.
b) Use the equation you have written above determine the cost for each bracelet. Show the algebraic steps that it takes to find the answer.
Now solving the equation to find the value of x that represent cost of each bracelet
9x + 9 = 72
Adding -9 on both sides
9x +9 -9 = 72 -9
9x = 63
Dividing both sides by 9
9x/9 = 63/9
x = 7
The value of x=7 so, the cost of each bracelet is $7
c) Provide your conclusion.
So, each bracelet was of cost $7 and $9 was the shipping charge. so, the total cost is $72.
We would check whether our equation is satisfied.
9x+ 9 = 72
9(7) + 9 = 72
63 + 9 = 72
72 = 72
The equation is satisfied.
Answer:
The point-slope form would be y - 4 = x - 2
Step-by-step explanation:
In order to find the equation of the line, we first need to find the slope. For that, we use the slope formula.
m (slope) = (y1 - y2)/(x1 - x2)
Now we plug the numbers into the equation.
m (slope) = (y1 - y2)/(x1 - x2)
m (slope) = (4 - -1)/(2 - -3)
m (slope) = 5/5
m (slope) = 1
Now we can use point-slope form along with the slope and either point to write the equation.
y - y1 = m(x - x1)
y - 4 = (x - 2)
The mixture contains 61.5% of water.
<u>Step-by-step explanation:</u>
Total parts = 4+ 2.5 = 6.5
Parts of water =4
parts of drink = 2.5
Percent of water in the mixture = 4 × 100/ 6.5
= 400/6.5
= 61.53%
It is rounded to the nearest tenth as 61.5%.
